magniX have launched a new electric engine range called HeliStorm, with features which open significant new opportunities for helicopter OEMs.

WIth electric engines for aviation applications typically running in the range of 1900-2500 RPM, the company’s new model runs much higher at 6000-7000 rpm, providing maximum power of 330KW.  The engine can be used on its own, or as part of a hybrid power solution, a turbo-generator etc.

The engine is direct drive, and thus without a gearbox, it provides 330kW at a very low weight.

In an interview with HeliHub.com, both CTO Riona Armesmith and CEO Reed Macdonald were keen to point out that there are many more applications which open up for magniX.  These include use as an APU for an airliner, a GPU for airports, an onboard range extender when required and so on.

“magniX has a proven track record when it comes to powering our R44 with their electric motors,” said David Smith, CEO of Robinson Helicopters. “Robinson is supportive of magniX’s HeliStorm electric engine range and we look forward to continuing our collaborative efforts to deliver market leading sustainable helicopters.”

Helicopter applications could see the engine replacing the engine on a single turbine, or as a hybrid solution for a twin-turbine.

The majority of magniX’s experience to date has been with the STC approach of changing the engine on an existing certified aircraft type, although their engines have also flown on clean sheet designs as well.

Just over eight months ago, magniX launched its game-changing battery line, named Samson after the Biblical character known for his extreme strength.  The Samson battery product raised the industry benchmark by a notable margin with an energy density of 300 Watt hours per kilogram (Wh/kg), and a quoted battery cycle life of over 1,000 full-depth discharge cycles.

Pairing the new engine with their Samson batteries provides a solution for magniX which is unmatched in the aviation industry.

Development of the engine builds on the company’s experience, which ranges from applications with Robinson R44s to the Electric Powertrain Flight Demonstration (EPFD) Program, where they partner with NASA.

Although Armesmith and Macdonald were unable to provide details of projects they are currently working on with OEMs, it was clear that they expect to be able to make some significant announcements from the company through 2025 and beyond.
